One-time monster Hurricane Irma has weakened to just a remnant circulation over Alabama but has left behind a plethora of astonishing weather records and statistics.

Below are some of the most stunning numbers that help quantify the magnitude of this storm and its impact, from the eastern Atlantic Ocean to Florida to Georgia and South Carolina.

16 million

The number of customers potentially without power in the Southeast, the most of any hurricane on record, doubling the 8.1 million in Superstorm Sandy. The 15 million outages in Florida represents three-quarters of its population.

Totals by state:

15 million outages in Florida

800,000 outages in Georgia

270,000 outages in South Carolina

37 hours

The number of hours the storm maintained maximum wind speeds of at least 180 mph, longer than any storm on Earth on record, passing Super Typhoon Haiyan, the previous record-holder (24 hours).


914 millibars

The pressure the storm dropped to on Sept. 5, (the lower the pressure, the stronger the storm), ranking as the lowest of any storm on record outside the Caribbean and Gulf of Mexico in the Atlantic basin. Irma’s landfall pressure of 929 millibars in the Florida Keys was the lowest for any U.S. landfalling hurricane since Katrina (920 millibars) and for a Florida landfall since Andrew (922 millibars). It ranks as the seventh-lowest pressure of any U.S. landfalling storm.


3 days

The length of time the storm remained a Category 5 hurricane, the longest since weather satellites began monitoring weather systems in 1966.
